Abstract: The present invention discloses a method for preparing an ibuprofen spherical crystal having high bulk density and a product thereof. The method includes: (1) heating ibuprofen until a molten liquid state is reached; and (2) pressurizing the molten liquid state of ibuprofen, dropping the molten liquid state of ibuprofen into a crystallizer filled with water through a liquid distributor for crystallization under stirring conditions until the molten liquid state of ibuprofen is completely dropped, lowering the rotation speed of stirring to allow crystal growing, and finally, subjecting a resulting crystal slurry to post-treatment to obtain the ibuprofen spherical crystal having high bulk density. The ibuprofen spherical crystal has a bulk density of 0.50-0.70 g/mL, a tap density of 0.63-0.89 g/mL, a median particle size of 300-1,000 ?m and an angle of repose of 22-29°.

Abstract: Disclosed by the present application are a method for controlling brightness in mobile terminal display, a mobile terminal and a storage device, the method comprising: controlling an optical sensor and an acceleration sensor within a mobile terminal to respectively monitor in real time a change value for environmental brightness and a change value for angle of rotation; determining whether the change value for environmental brightness and the change value for angle of rotation as monitored by the mobile terminal are less than a preset brightness and a preset angle, respectively; and when yes, controlling the brightness in mobile terminal display to not change.

Abstract: The disclosure belongs to the field of tunnel construction technologies, and more particularly, relates to a construction method for making a water-rich sand layer shield over cross an existing line and underneath cross a sewage push pipe at a close range. The method specifically includes the following steps of: S1) before construction, using MIDAS GTS NX software and FLAC3D to optimize a tunneling scheme antecedently by numerical simulation to determine a part of unfavourable stress; S2) tunneling a test section, the test section being a stratum crossing a front shield direction by 45 m to 60 m; and S3) performing shield crossing construction, wherein a shield crossing construction process includes the steps of: 1) controlling a soil pressure; 2) controlling a shield thrust; 3) performing synchronous grouting; 4) performing a ballasting measure in a tunnel; and 5) performing automatic monitoring in the tunnel.

Abstract: A mobile terminal, a method of controlling a Doze mode of a mobile terminal, and a computer-readable non-transitory storage medium may be provided. The method includes: detecting whether the mobile terminal is in the Doze mode; in response to the mobile terminal in the Doze mode, activating the accelerometer to sense a particular motion change; and in response to the particular motion change reaching a predefined threshold, deactivating the Doze mode.

Abstract: Disclosed in the present invention are a method and system for selecting VOLTE according to an SIM card by a mobile terminal, and the mobile terminal. The method comprises: establishing a relationship table between a PLMN of a preset SIM card and ID values; performing a dynamic search by means of the PLMN of an SIM card; querying, in the relationship table, to determine whether the PLMN exists and whether the PLMN needs to be updated; when the PLMN exists and needs to be updated, obtaining an ID number of a current SIM card according to the relationship table; and when the PLMN does not exist, obtaining a default ID value; and obtaining a related configuration parameter according to the obtained ID.
